Abstract

68.47.Pe 74.78.-w 82.65.+r
The study of the effect of self-assembled organic monolayers on the critical current in thin superconducting Nb films is presented. Correlation is found between the coverage of the adsorbed layer and the critical current. A large change of up to 50% in the critical current by the well-organized monolayers is observed. The phenomenon is explained by the adsorption-induced electric field effect diminishing the surface pinning force.
